This invention relates to machines for forming oil grooves and pocketsin the bearan arrangement permitting adjustment of the structure to accommodate bearings of different diameters andfdifierent widths and of means for mounting the connecting rods for an operation which-means is adjustable so that rods of different sizes may be taken care of. '1 A still further object of the invention is to provide a device of this character which is simple in its construction and arrange-' ment, which will bedurable in service and which may be readily and cheaply manu-' factured.

These and other objects I attain bythe construction shown in the accompanying draw ings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein I Figure 1 is a side elevation partially in section ofa bearing grooving and pocketing machine constructed inaccordance with my."

Referring now more particularly to the drawings, thenumeralflO indicates a suitable base having arislng-therefrom bearings 11 in which isdisposeda cutter'shaft 12. i This shaft may be rotated in any suitable manner, being at present shown as provided with a pulley'13 for; operation by a belt from a suitable source of power. Opposite ends of the shaft aresocketed, as at 14 and15, for the reception of cutter mandrels. In Figure 1,

the socket 14 is shown'as having'disposed therein a mandrel 16 provided with a broad faced cutter 17,the purpose of which will hereinafter appear. I

For this mandrel may be substituted a mandrel 18 having a narrow faced cutter 19 for the performance of special work. The socket15 mounts a mandrel 20 having a narrow faced cutter 21 similar to the cutter 19 and this mandrel may be removed and other 7 mandrels of different sizes substituted, when so desired.-- Associated with the mandrel 1-5 andarising from-the base 10 area pair of brackets 22, each having, a horizontal upper end 23 from which arises a pin 24. The pins 2 1 are diagonally disposed with relation to each other and arranged at opposite sides of the general, plane of the cutter as more clearly shown in Figure 8, and are spaced to extend into the openings 25 in thecrank bear- Figure 9. I I I It will be obvious that these pins will maintain the bearingat an angle with the result that the face thereof, when the bearing is forced downwardly upon the pins, will enconnecting rod 26 as shown in gage with the cutter 21 and have formed therein a diagonally extending oil groove 27,

as more clearly illustrated in Figure 9. It will beobvious that by substituting for the cutter 21. and its mandrel 20 a cutter of the proper size, such grooves may be formed in bearings of any desired diameter.

The mandrel 16 overhangs one end of the base and at this end, as shown in Figure 11 the base is provided adjacent its lower end witha pair of vertically extending guides 30 between which is mounted the shank portion 31 of a wrist pin 32. Rotatably mounted be tween the guides is a threaded stem 33 which with the pin 32.

Adjustment to com ensate for the width of the connecting rod eing acted upon may be had by means of washers 36 or other suit able devices. The pin 32 acts as a pivot for the connecting rod, permitting the same to be oscillated from one side to the other, sothat the cutter may act upon opposite faces thereof to form the oil pockets 37, as shown in Figure 7- in the bearing, which do not extend through the side faces of the bearing. By the adjustment at 33, the height of the bearing may be so regulated that this pocket is equally distributed between the two sections in which such bearings are ordinarily formed.

In addition to the diagonal type of oil groove, the bearings are provided with transverse grooves, some ofwhich, as illustrated in Figures 4 and 5, as at 38, open through the side faces of the bearings and others of which, as indicated in Figure 9 at 39, terminate short of the edges of the bearings. Each of these grooves is formed by use of the mechanism more particularly illustrated in Figure 3and shown in partial cross section in Figure 1. This mechanism includes a standard 4L0 arising from one side of the base and having pivoted to its upper end a table 41. 'At its free edge, the table has legs 42 which are adjustable as to length and are adapted to engage theupper surface of the base to determine the effective height of the table at the middle thereof. The middle of the table has an opening 43 through which extend the diagonally disposed cutting faces 44 of a compound reamer secured to the shaft 12. To the upper surface of the table is removably secured a transversely extending semi-circular bar 45, which may be removed and replaced with bars of different sizes. This bar at its middle is notched, as indicated at 4:6, to accommodate the periphery of the reamer and to expose the cutting faces thereof.

It will be obvious that the vertical height of the table will determine the extent to which the reamer faces are exposed and by placing aproper bar 45 to interiorly lit the bearing section, this hearing section may be slid over the reamer as it is in operation to form the cut or oil groove of Figures 1 and 5. To form an oil groove, such as shown at 39 in Figure 9, the bearing section is simply forced vertically downwardly upon the reamer.

It will be obvious that by use of apparatus of this character, practically any grooving or pocketing operation desired can be performed and tllGOPQIELtlOIl will require but a very short time.

Since considerable modification might be resorted to without in any manner departing from the spirit of my invention, I do not limit myself to the specific structure hereinbefore set forth except as hereinafter claimed.
